Shouldn't be the case. How often are you cleaning them? I wipe mine down every 2 to 3 days. A few spritz of TurtleWax-as-you-dry on the wheels and wipe away. Easy.

Honestly every couple of weeks b/c its a daily driver. I don't have time to wash/wipe the rims constantly. It is just not in the pictue. I thought there might be something easier to clean the lips when I finally get around to doing it. Don't get me wrog the mother's does a great job, but it takes time and effort and I thought there might be a better way.
